How to calculate 91 multiplied by 51

How to calculate 91 multiplied by 51 using long multiplication. Here is step-by-step how to calculate 91 times 51 using long multiplication:

Step 1: Setup
Set up your multiplication problem like this:

	9	1
x	5	1

Step 2: Multiply
1 x 1 = 1. Put 1 below the line and 0 as a reminder on top:

	0
	9	1
x	5	1
		1

Step 3: Multiply
1 x 9 = 9. Take 9 and add 0 from the previous step to get 9. Enter 9 at the bottom:

	9	1
x	5	1
	9	1

Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:

	9	1
x	5	1
	9	1
+		0

Step 5: Multiply
5 x 1 = 5. Put 5 below the line and 0 as a reminder on top:

Step 6: Multiply
5 x 9 = 45. Take 45 and add 0 from the previous step to get 45. Enter 45 at the bottom:

			9	1
x			5	1
			9	1
+	4	5	5	0

Step 7: Add to get answer
Add up the bottom two numbers (91 + 4550 = 4641) to get the answer:

			9	1
x			5	1
			9	1
+	4	5	5	0
=	4	6	4	1

The bottom line is the answer. Therefore, 91 times 51 equals:
